The rest of the report is structured as follows:
	
\begin{description}
	\item[Chapter \ref{chapter:gpgpu}] introduces general purpose computations on GPUs (GPGPU). The history and current state of GPU computing is presented, and the recent OpenCL architecture for GPGPU is described.
	\item[Chapter \ref{chapter:3d_ultrasonography}] introduces the field of 3D ultrasonography. Methods of reconstructing volumes from ultrasound scans and techniques to visualize the ultrasound volume are described. Related work in the field is also presented, with special focus on work that this thesis builds upon.
	\item[Chapter \ref{chapter:gpu_reconstruction}] describes the approach used in this thesis where the GPU is utilized to perform fast reconstruction of ultrasound scans acquired beforehand. Both voxel-based and pixel-based reconstruction is described.
	\item[Chapter \ref{chapter:incremental_reconstruction_visualization}] describes how real-time incremental reconstruction and volume visualization can be performed on the GPU simultaneously as the data is acquired. A simple PNN based method and an advanced high quality probe trajectory based method is described.
	\item[Chapter \ref{chapter:results_discussion}] presents the performance and quality of the ultrasound reconstruction and visualization as performed in this thesis. These results are also discussed.
	\item[Chapter \ref{chapter:conclusion_future_work}] concludes the thesis and presents future work.
